1. From quantum geometry to Fisher information

Gunnar Felix Lange (UiO)

Quantum sensing relies on an unknown parameter being encoded in a quantum state, which is read out and measured.

One interpretation of this encoding is geometrically, where we consider the quantum system to live on a space parameterized by the parameter. The distance on this space is then linked to the Fisher information, giving the maximal attainable sensitivity of the sensor. This gives a...

2. Modeling superconducting-qubit processors and simulators beyond 100 qubits

Simon Pettersson Fors (Chalmers)

25/06/2026, 09:45

As superconducting quantum processors scale beyond 100 qubits, new theoretical tools are required to model their complex, many-body dynamics. In this talk, we introduce a scalable, non-perturbative renormalization method using continuous unitary transformations to systematically derive effective Hamiltonians. This method efficiently eliminates weakly coupled degrees of freedom, capturing the...

4. Doping-induced quantum spin liquids: Towards robust topological order for quantum technology

Cecilie Glittum (UiO)

25/06/2026, 10:00

Quantum spin liquids provide a natural platform for robust topological order and fractionalised excitations, but realising such phases in realistic quantum magnets has remained a long‑standing challenge. In this talk, I will introduce the concept of quantum spin liquids, and show how dilute hole doping of a half‑filled Mott insulator on corner‑sharing tetrahedral lattices leads to a quantum...

5. Generation and Characterization of Nonclassical Light for Quantum Technology

Kishore Thapliyal (UiO)

25/06/2026, 10:45

Quantum enhancement in computation, communication, and sensing relies on the generation and control of nonclassical states. Generation of such photonic nonclassical states useful for quantum technology is discussed in the context of quantum state engineering and reservoir engineering. Quadratic Hamiltonians generate and preserve Gaussian states, whose dynamics are completely determined by the...

6. Quantum simulation with giant atoms

Guangze Chen (Chalmers)

25/06/2026, 11:00

Superconducting quantum processors require hardware platforms that combine scalability with flexible multi-qubit interactions. Here, we show how giant atoms, artificial atoms coupled to a waveguide at multiple spatially separated points, enable interference-engineered quantum interactions through phase-controlled coupling to propagating photons. By exploiting quantum interference, giant atoms...

7. Nanophotonic Spectral Transduction for Reliable Readout of Local Molecular and Quantum Excitations

Zhiyuan Hedlund (EPFL)

25/06/2026, 11:15

Many molecular, nanoscale, and quantum systems are accessed experimentally through spectra. Spectral features such as peak position, linewidth, splitting, intensity ratio, and polarization dependence encode allowed transitions, coupling strengths, lifetimes, dephasing, selection rules, and local environmental perturbations. However, when these weak local excitations are read through a...

8. Experimental demonstration of non-local magic in superconducting quantum processor

Jovan Odavić (University of Naples Federico II)

25/06/2026, 11:30

Magic is a non-classical resource whose efficient manipulation is fundamental to advancing efficient and scalable fault-tolerant quantum computing. Quantum advantage is possible only if both magic and entanglement are present. Of particular interest is non local magic - the fraction of the resource that cannot be distilled (or erased) by local unitary operations - which is a necessary feature...
